A review of advances in multifunctional XTiO3 perovskite-type oxides as piezo-photocatalysts for environmental remediation and energy production

A Novel Strategy for Excellent Piezocatalytic Activity in Lead-Free BaTiO3-Based Materials via Manipulating the Multiphase Coexistence

“…The rapid development of industry and global population has brought severe water environmental problems, especially water pollution. , There is an urgent need to develop some environmentally friendly, efficient, and renewable methods for water remediation. Recently, the piezocatalytic technique used in the degradation of organic pollutants has been one of the researching hotspots − because piezocatalysis exhibits high degradation efficiency and can be used in some special occasions compared with other techniques. For example, exploiting ultrasound-based mechanical vibration can realize the remote activation of piezocatalysts, which can be applied to biotherapy …”

High efficiently harvesting visible light and vibration energy in (1−x)AgNbO3–xLiTaO3 solid solution around antiferroelectric–ferroelectric phase boundary for dye degradation

“…Perovskite oxide materials have gained much attention because of their unique structure, semiconductor, and light-harvesting properties [36,37]. The average structure of silver niobate (AgNbO 3 ) at room temperature still remains controversial because it can be reasonably fitted by either Pbcm or Pmc2 1 space group [38][39][40][41].…”

Piezoelectric catalytic performance of BaTiO3 for sulfamethoxazole degradation

“…Metal ions, metal oxides, and carbon-based materials are some of the most commonly used catalysts. [8][9][10][11] For piezoelectric materials, various forms of mechanical energy, for example, ultrasound and hydraulic dynamic energy, can be converted into electrical energy or chemical energy. Since direct watersplitting using the piezoelectric effect was discovered by Hong et al, 12 piezoelectric catalysis has been receiving increasing attention as a novel advanced oxidation process (AOP).…”
